		                        			OBJECTIVE To excavate the adverse drug event (ADE) signals of three third-generation tetracycline antibiotics (tigecycline, omadacycline, eravacycline) based on FDA adverse event reporting system (FAERS), and to provide reference for the safe use of them. METHODS The ADE reports of tigecycline, omadacycline and eravacycline from the first quarter of 2005 to the second quarter of 2023 were retrieved from FAERS database. The ADE signals of 3 kinds of drugs were mined by the method of reporting odds ratio method and the proportional reporting ratio method. RESULTS Totally 2 538 ADE reports with tigecycline, omadacycline and eravacycline as the primary suspected drugs were obtained, including 2 135 tigecycline ADE reports, 349 omadacycline ADE reports and 54 eravacycline ADE reports. A total of 131 ADE positive signals of tigecycline were mined, involving 19 system organ classes (SOCs), mainly concentrated in investigations, hepatobiliary system, blood and lymphatic system, and gastrointestinal system, etc; the preferred terminologies (PT) with intense signal were hypofibrinogenaemia and blood fibrinogen decreased. Fourteen ADE signals were not mentioned in the drug instruction, such as renal failure, acute kidney injury and hemorrhage. Totally 24 ADE positive signals of omadacycline were mined, involving 6 SOCs, mainly concentrated in the gastrointestinal system and various examinations; the PTs with intense signals were tooth discoloration, jet-like vomiting and loose feces, etc. ADE signals were not mentioned in the drug instructions, included lip swelling, gastroesophageal reflux disease, eosinophilia, skin discoloration, feces softening, and night sweats. Five ADE positive signals of eravacycline were mined, involving 4 SOCs, mainly concentrated in various examinations, gastrointestinal system, etc. The most intense ADE signals were blood fibrinogen decreased and hypofibrinogenaemia. CONCLUSIONS ADE of the gastrointestinal system are mostly identified in the three third-generation tetracycline antibiotics, especially pancreatitis caused by tigecycline and gastroesophageal reflux disease caused by oral administration of omadacycline. The liver function, renal function (for tigecycline) and coagulation function (for tigecycline, eravacycline) should be monitored biyiliang@hotmail.com regularly during medication, so as to prevent the occurrence of serious ADE.

		                        			Objective:To investigate the effect of specnuezhenide on high glucose-induced human retinal microvascular endothelial cells (hRMECs) injury and its mechanism.Methods:The hRMECs were divided into a normal control group cultured in a culture medium containing 5.5 mmol/L glucose, a hypertonic group cultured in a culture medium containing 5.5 mmol/L glucose + 24.5 mmol/L mannitol, a high glucose group cultured in a culture medium containing 30 mmol/L glucose, as well as high glucose+ low-, medium-, and high-dose specnuezhenide groups cultured in culture media containing 30 mmol/L glucose + 25, 50, 100 μmol/L specnuezhenide for 24 hours, respectively.In addition, hRMECs were divided into a high glucose+ small interfering RNA-negative control (si-NC) group cultured in a culture medium containing 30 mmol/L glucose, a high glucose+ si-forkhead box O4 (FOXO4) group cultured in a culture medium containing 30 mmol/L glucose, a high glucose+ specnuezhenide+ pcDNA group cultured in a culture medium containing 100 μmol/L specnuezhenide + 30 mmol/L glucose, and a high glucose+ specnuezhenide+ pcDNA-FOXO4 group cultured in a culture medium containing 100 μmol/L specnuezhenide+ 30 mmol/L glucose for 24 hours after transfection by corresponding reagents.Cell apoptosis was detected by flow cytometry.The malondialdehyde (MDA) concentration and superoxide dismutase (SOD) activity in cells were detected by the thiobarbituric acid method and xanthine oxidase method, respectively.The concentrations of interleukin (IL)-1β and tumor necrosis factor (TNF)-α in the cell culture supernatant were detected by enzyme linked immunosorbent assay.The relative expression level of FOXO4 protein in cells was determined by Western blot.Results:The apoptosis rates of normal control group, hypertonic group, high glucose group, high glucose+ low-, medium- and high-dose specnuezhenide groups were (7.32±0.72)%, (7.44±0.70)%, (23.96±1.32)%, (19.84±1.09)%, (14.13±0.85)% and (9.84±0.70)%, respectively.There were significant differences in cell apoptosis rate, MDA concentration, SOD activity, the concentration of IL-1β, the concentration of TNF-α, and the relative expression level of FOXO4 protein among the six groups ( F=498.545, 1 186.693, 516.629, 654.247, 638.238, 472.655; all at P<0.001). Compared with high glucose group, the apoptosis rate, MDA concentration, IL-1β and TNF-α concentration, FOXO4 protein expression level were significantly decreased in high glucose+ low-, medium- and high-dose specnuezhenide groups, and SOD activity was significantly increased in a dose-dependent manner.Compared with high glucose+ si-NC group, the expression level of FOXO4 protein, cell apoptosis rate, MDA concentration, IL-1β and TNF-α mass concentrations were decreased in high glucose + si-FOXO4 group, while the SOD activity was increased.Compared with high glucose+ specnuezhenide+ pcDNA group, the apoptosis rate, MDA concentration, IL-1β and TNF-α concentrations, FOXO4 protein expression level of hRMECs in high glucose+ specnuezhenide+ pcDNA-FOXO4 group were significantly increased, and SOD activity was significantly decreased (all at P<0.05). Conclusions:Specnuezhenide can protect hRMECs from high glucose-induced apoptosis, oxidative stress and inflammatory response by down-regulating FOXO4.

Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.

		                        			Objective:Partial stereotactic ablative boost radiotherapy(P-SABR)is a method to deliver SABR boost to the gross tumor boost volume(GTVb), followed by conventionally fractionated radiotherapy to the whole tumor area(GTV). GTVb is the max volume receiving SABR while ensuring the critical organ-at-risk(OAR)falloff to 3 GyE/f. We investigated the potential advantage of proton therapy in treating bulky non-small cell lung cancer(the tumor length greater than 8 cm).Methods:Nine patients with bulky NSCLC treated with photon P-SABR in our institute were selected. For the treatment planning of proton therapy, the GTVb target area was gradually outwardly expanded based on the photon GTVb target area until the dose to critical OARs reached 3 GyE/f. The GTV and CTV areas remained the same as photon plan. A proton intensity-modulated radiation treatment plan(proton-IMPT), a photon intensity-modulated radiation treatment plan(photon-IMRT)and a photon volumetric modulated arc therapy(photon-VMAT)were created for each patient, respectively. The dosimetric parameters of different treatment plans were compared.Results:The volume ratio of GTVb-photon and GTVb-proton to GTV was(25.4±13.4)% and(69.7±30.0)%,respectively( P<0.001). In photon-IMRT, photon-VMAT, and proton-IMPT plan groups, the mean dose of CTV was(76.1±4.9)Gy, (78.2±3.6)Gy, and(84.7±4.9)Gy, respectively; the ratio of tumor volume with Biologic Effective Dose(BED)≥ 90 Gy to GTV volume was(70.7±21.7)%, (76.8±22.1)%,and(97.9±4.0)%,respectively. The actual dose and BED to the tumor area of the proton-IMPT plan group were significantly higher than those of the photon plan group(both P<0.05). Besides, the OARs dose was significantly decreased in the proton-IMPT group, with(49.2±22.0)%, (56.8±19.0)% and(16.1±6.3)% of the whole lung V5 for photon-IMRT, photon-VMAT and proton-IMPT, respectively(all P<0.001). Conclusions:Larger GTV boost target volume, higher BED and reduced OARs dose can be achieved in proton plans compared with photon plans. Proton P-SABR is expected to further improve the local control rate of bulky NSCLC with fewer adverse effects.

		                        			OBJECTIVE To study the protective effect of phenolic acid components from Salvia deserta Schang on the oxidative stress injury of human renal tubular epithelial cells HK -2 induced by high glucose and high fat . METHODS HK-2 cells were divided into control group ,model group ,canagliflozin group (positive control group ,15 μmol/L),purified product of phenolic acids from S. deserta Schang group (10.8 μg/mL),4 monomers group (salvianic acid ,protocatechuic aldehyde ,caffeic acid,rosmarinic acid ,50 μmol/L). In addition to the control group ,cell injury model of high glucose and high fat was established in other groups (500 μmol/L palmitic acid+ 30 mmol/L glucose for 48 h)and cultured for 48 h. The cell apoptotic rate ,the contents of malondialdehyde (MDA)and glutathione (GSH),and the activity of superoxide dismutase (SOD)were detected in each group ; the expression levels of nuclear erythroid 2-related factor 2(Nrf2),Kelch-like ECH -associated protein 1(Keap1)protein,heme oxygenase-1(HO-1)and NADH :quinone acceptor oxidoreductase 1(NQO1)were determined in above 5 groups(except for salvianic acid ,protocatechuic aldehyde ,caffeic acid ). RESULTS Compared with control group ,the apoptotic rate of HK -2 cells in model group was increased significantly (P<0.01);the content of MDA was increased significantly (P<0.01),while the content of GSH and the activity of SOD were decreased significantly ;protein expressions of Nrf 2,NQO1 and HO -1 2018D01C169) were significantly down -regulated(P<0.01),while the protein expression of Keap 1 was up -regulated significantly (P<0.01). Compared with model group , the apoptotic rate and the content of MDA were decreased significantly in administration groups(P<0.01);the content of GSH in administration groups and the activity of SOD in purified product of phenolic acids group,protocatechuic aldehyde group and rosmarinic acid group were increased significantly (P<0.01). The protein expressions of Nrf2,HO-1 and NQO 1 in purified product of phenolic acids group as well as the protein expression of Nrf 2 in rosmarinic acid group were up -regulated significantly (P<0.01),while the protein expression of Keap 1 was down -regulated significantly in purified product of phenolic acids group and rosmarinic acid group (P<0.01). CONCLUSIONS The phenolic acids components from S. deserta Schang can relieve oxidative stress injury of renal tubular epithelial cells induced by high glucose and high fat ,the mechanism of which may be associated with activating Keap 1/Nrf2 signaling pathway and inhibiting oxidative stress response .
